I have an issue with my lawn... On the East side of my home which gets about 7-8 hours sun each day is turning brown. I really don't think that it is going dormant, because the rest of my yard is pretty green. I am using a Lesco 28-0-3 fert about every 45 days. I have irrigation and I am watering 4 days a week and have plenty of coverage. I know I am going to have to do some soil tests to figure out what is going on but I was hoping someone might be able to look at it and be able to say "Hey that's...." I also have a weed that has been coming into my yard fro my neighbors lawn... Celsius at the med rate and a surfactant is not touching it. any clue what it might be? Any help would be greatly appreaciated.
